国外早在四十年代末和五十年代初钛的冶炼发展初期,就同时重视钛的粉术冶金工艺的研究。美国1952年报导过有关钛粉热锻、冷压烧结、等静压、粉浆浇注、热压等工艺的试验,但由于技术难度较大,进展缓慢。直到1970年美国三家航空公司取得重要的技术突破,在1971年的国际粉末冶金会议上被赞誊为粉末冶 Abroad as early as the late 1940s and early 1950s when the development of titanium smelting at the same time attach importance to titanium powder metallurgy technology research. The United States reported in 1952 on the titanium powder hot forging, cold-pressed sintering, isostatic pressing, slip casting, hot pressing and other tests, but due to technical difficulties, progress is slow. Until 1970, three U.S. airlines made important technological breakthroughs and were praised for powder metallurgy at the 1971 International Powder Metallurgy Conference
